ABSTRACT
Background; The vulnerability of immunosuppressed populations, including transplant recipients, to infectious diseases has been brought to light once more by the COVID-19 pandemic. The purpose of this study was to look into any possible relationships between COVID-19 and post-transplantation results in liver and kidney transplant recipients. Material and methods; Individuals who had undergone liver and kidney transplants and tested positive for COVID-19 underwent a retrospective review of their medical records. Patient demographics, transplant characteristics, immunosuppressive therapy, and COVID-19 results were all recorded. Then, nasopharyngeal swab samples were utilized for the whole genome sequencing on the Nanopore NGS platform. Logistic regression analysis was used to evaluate the association among transplant-related Immunosuppression, biological biomarkers, and COVID-19 susceptibility. Results; The study found a potential correlation between COVID-19 and adverse post-transplantation outcomes in liver and kidney transplant patients. Higher D-dimer in liver transplant patients was seen (p = 0.003). There was also significant rise in RBC (p=0.047), Hb (p=0.027), and Htc (p=0.008) after transplantation. Discussion and conclusion; The present study provides valuable insights into the potential correlation between COVID-19 and post-transplantation outcomes in liver and kidney transplant patients. The management of transplant recipients during the COVID-19 pandemic would benefit from the current study's findings.

COVID-19 resulted from an infection by SARS-Cov-2 which is the main cause of ADRS in global population from 2019 on. It may contribute to higher rate of death among the patients with immunodeficiency based on recent reports. In addition, Good syndrome (GS) as a result of thymoma removal might cause in some long-lasting microbial infections. We described clinical aspects and viral mutations on a case of GS suffering from COVID-19. A 46-year-old man with fever, general respiratory signs and positive COVID-19 PCR test, with the history of thymoma removal surgery was admitted to Masih Daneshvari Hospital, Tehran, Iran. Lung radiographs and Oxygen saturation measurement disclosed considerable implication resulted in application of several anti-microbial medication. The delta variant (B.1.617.2 (21J Clade)) was the strain isolated from the patient by sequencing methods done by CNRL while the dominant strain circulated mostly among population was Omicron (B.1.1.529) at the time of sampling. Unfortunately, the patient had passed away a month later by sudden respiratory failure progressed in refractory septic shock. Despite the fact that opportunistic infections may lead the GS patients to a major health problematic condition, unusual persistent of infections such as non-dominant variant of SARS-Cov-2 could be observed through the disease timeline. Therefore, a fully screening of thymoma plus intra-host evolution monitoring of SARS-CoV-2 is highly recommended in immunocompromised patients.
